In order to ensure the normal operation of concrete mixing plant and give full play to its benefits, normal maintenance of concrete mixing plant should be carried out. How often is the concrete mixing plant maintained?
As the growing demand for concrete, concrete production work is also continuously increased. To guarantee the concrete mixing plant daily normal operation, the key is to regularly maintain the concrete plant and it’s not only related to the project progress, but also has close ties to project earnings also. In order to ensure the normal operation of concrete mixing plant and give full play to its benefits, the normal maintenance of concrete plant should be carried out. How often is the concrete mixing plant maintained?
1.Check before each use of concrete mixing plant
Check whether the air compressor self-protection device is reliable and the air pressure is stable. Check whether the water pump is sufficient and the pipeline is unimpeded.Whether the hopper door, cement hopper door, middle aggregate hopper door and discharge door are flexible and reliable.Check whether the connecting bolts of the agitator blade are firm. Check whether the electrical devices are safe and reliable, and whether the limit switches are flexible and reliable. Check whether there is enough lubricating oil in each lubrication point of deceleration box.
2. Maintenance after each shift
Clean the accumulated material on the concrete mixer inside and outside and the material door, and wash it thoroughly. Add lubrication points at each lubrication point, especially at the seal of the shaft end. In winter, the liquid in the water purification system should be released. Exhaust the gas and water in the air cylinder of the air compressor. All the switches are not working after the stop and the power supply is cut off.
3. Check and maintain weekly
Check of the residual concrete mixing tank condensation conditions, such as setting should stop to root out (note shall be cut off power supply specialist care), check the mixing blades and liner clearance, adjust them if not suitable. Check whether the air path system leaks air and the cylinder operates reliably. Check the quality and level of the lubricating oil in the reducer, add or replace it if necessary.Check whether the suction bottom valve in the water supply system is reliable. Check whether the electrical components are damaged, repair or replace them if necessary.And check whether the wiring is loose. Unscrew the blockage and check the seal condition of the shaft end. If no abnormality, screw in the blockage.
4. inspect and maintain it around
Check the belt tension and make appropriate adjustment. Check the wear condition of blade and liner. Check whether the connecting bolts of upper and lower frame, material bin, large inclined belt machine and other parts are firm, and whether the foundation is sinking. Check whether there are any lumps and sundries in the screw conveyor, if any, remove them.
5. Inspect, maintain and overhaul the concrete mixing plant every year
In addition to checking 1, 2, 3 and 4 items, the equipment should also be inspected for other parts and comprehensively inspected for repair and replacement.
